You can move the position of the shift towers on these transmissions to come out within 1/2” of a Healey center-shift stick. But, you cannot change the fifth gear to change the ratio. Fifth gear is part of a complete different set of gears. <div><br></div><div><br id="lineBreakAtBeginningOfMessage"><div>

That .73 gear is essential, and after a couple of miserable weeks with the .63 gear, I told them so. They were extremely gracious in getting me the .73 replacement and a local transmission shop made the swap. Sorry to hear there’s a wait for that gear now, but obviously others came to the same conclusion that the .63 is way too steep for the Healey. Some simple math would have saved me some trouble: fifth gear ratio x rear end ratio for the ultimate, final drive, and it’s obvious that .73 is about all you want with the 3.91 rear and even the 4.10 on the 100/6. And I think even the .73 would be too much with a 3.54 rear; there should be a .88 or so gear for the Tremec T5, which I’d pick that that rear. <br><br><br><div class="yahoo-signature"><a style="font-size:12px" href="https://aolapp.onelink.me/eG2g?pid=NativePlacement&c=US_Acquisition_YMktg_320_EmailSignature_AttributionDL&af_sub1=Acquisition&af_sub2=US_YMktg&af_sub3=&af_sub4=100002473&af_sub5=SentFromNewAOLApp__Interstitial_&af_ios_store_cpp=ce85ce34-ad0f-4811-a92b-a172743b064e&af_android_url=https%3A%2F%2Fplay.google.com%2Fstore%2Fapps%2Fdetails%3Fid%3Dcom.aol.mobile.aolapp%26listing%3Demail_signature_attribution">Sent from the all new AOL app for iOS</a><br></div><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: rgb(132, 115, 255); padding-top: 15px; margin-top: 0px;">On Saturday, October 18, 2025, 5:52 PM, Al Fuller <alfuller194@gmail.com> wrote:</p><blockquote class="iosymail"><div id="yiv2389198767"><div><div><div>The tremec conversion is supposed to be nice, but one of the guys has been waiting for months for them to get that particular gear.</div><div><br clear="none"></div><div>I've lost track of whether they finally got a batch.</div><div><br clear="none"></div><div>________________<br clear="none">Sent from my phone <br clear="none">Best Regards,<br clear="none">Al Fuller</div></div><br clear="none"><div class="yiv2389198767gmail_quote yiv2389198767gmail_quote_container"><div id="yiv2389198767yqt80001" class="yiv2389198767yqt3310884849"><div dir="ltr" class="yiv2389198767gmail_attr">On Sat, Oct 18, 2025, 5:22 AM Robert Markovich via Healeys <<a rel="nofollow noopener noreferrer" shape="rect" ymailto="mailto:healeys@autox.team.net" target="_blank" href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br clear="none"></div><blockquote style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;" class="yiv2389198767gmail_quote"><div>
Try The Driven Man in Cooksville TN. They make kits for Healey Sixes and Jags using a brand new Tremec T5. Just be sure and order the .73 fifth gear ratio as the standard .63 is way too steep.
